From KAVAN RC Wiki

Start with the tail boom. Glue it on the building board in order to make the tail boom true and straight. Glue the front balsa block 20 to the spruce stick (2×8×600 mm) 22 taking care the outer edges of the block matched the edges of the stick.

Note: The rear balsa block 21 will be glued to the bevelled side of the front block later.
